How old is the crater Copernicus?
800 million years old
Later, material believed to be Copernicus ejecta was sampled by Apollo 12 astronauts, and these samples were radiometrically dated to be close to 800 million years old.
Where is the crater Copernicus on the moon?
Located at 10° N, 20° W, near the southern rim of the Imbrium Basin (Mare Imbrium) impact structure, Copernicus measures 93 km (58 miles) in diameter and is a source of radial bright rays, light-coloured streaks on the lunar surface formed of material ejected by the impact.
How deep is the Copernicus crater?
2.4 miles
Copernicus is believed to be a lunar impact crater, formed by the collision from the fragment of an asteroid some 800 million years ago. It’s a circular crater measuring 58 miles (93 kilometers) across and 2.4 miles (3.8 km) deep.
What type of crater is Copernicus?
Copernicus is a lunar impact crater located in eastern Oceanus Procellarum. It was named after the astronomer Nicolaus Copernicus. It typifies craters that formed during the Copernican period in that it has a prominent ray system.
How old is the Archimedes crater?
The crater – ‘walled plain’ would be a better description – belongs to what is known as the Imbrian period, which extended from 3.1 to 3.85 billion years ago, and it is of course an impact structure.
How old is the Kepler crater?
Crater Kepler (32 km in diameter) has intermediate age [3]. It is younger than Copernicus (inferred age of ~ 810 Myr), but older than Tycho (inferred age of ~ 109 Myr). It’s needed to note that crater Kepler placed on the background formation that is possibly part of highland near crater Copernicus.
How old is Mare Imbrium?
about 3.85 billion years ago
The Imbrium Basin is also the second youngest basin on the Moon. Based on samples returned by Apollo 15, it formed about 3.85 billion years ago. This image provides an overview of the Mare Imbrium region, which occupies the upper left portion of the image.
Is Kepler a moon?
Like several moons in the Solar System, the large exomoon would theoretically be able to host its own moon, called a subsatellite, in a stable orbit, although no evidence for such a subsatellite has been found….Kepler-1625b I.

How did mare Humorum form?
Origin. Mare Imbrium may have been formed when a proto-planet from the asteroid belt collided with the moon 3.8 billion years ago.
What was the first crater?
Yarrabubba Crater was blasted out by an asteroid or comet about 2.23 billion years ago. Scientists have identified the oldest known impact crater on Earth — and the ancient structure could tell us how our planet emerged from a long-ago frozen phase.
